This is the boost controller I went with:


I bought it open-box from ebay, so I wanted to make certain it wasn't busted up so I took it apart. This is what is inside. This one is indeed new.








For those wondering how this works, it is a bleed-off type boost controller. That means it will bleed off a preset amount of air going to the wastegate.
This controller has two stages of bleed-off, controlled by a switch. The only electronic part in this system is the solenoid that opens the path to the second bleed dial. It appears it would work fine as a single-stage without any 12v signal.

The dials are reverse threaded. Turning counter-clockwise closes the bleeder valves. Turning clockwise opens the bleeder valves to increase boost.

I have not installed this yet. I ordered a vacuum block and it won't be here until later this week. I'm going to clean up some vac/boost lines so my boost gauge, boost controller and bov all get the signal from the same vac block.
I'm going backpacking/flyfishing for a few days next week, so don't expect any updates until after.
